Limiting the number of characters in a string, and chopping off the rest

You can also use String.format("%3.3s", "abcdefgh"). The first digit is the minimum length (the string will be left padded if it’s shorter), the second digit is the maxiumum length and the string will be truncated if it’s longer. So

System.out.printf("'%3.3s' '%3.3s'", "abcdefgh", "a");

will produce

'abc' '  a'

(you can remove quotes, obviously).
